I stopped drinking Thursday night around 12... had maybe 7 beers... I know for a fact my bac was zero at 8 am Friday am... I will have an ETG on Wednesday at 8am... I did have three O'Douls during the weekend... but that is it... I have drank a decent amount of water... just wonderiing if I am in the safe zone? If you are out their Dr Bill, your opinion would be appreciated
